A bromeliad, not a tree or even a bush. Grows as a rosette of spiky leaves at ground level and produces a single fruit on a central stalk. Propagated from the crown (leafy top of fruit), suckers, or slips from the mother plant. Takes 18-24 months from planting a crown to first fruit. Each plant produces ONE fruit then generates suckers for subsequent crops. Strictly tropical/warm subtropical. Frost kills them.
